· JVASP-101723· Fe4Se3Br

Fe4Se3Br is an experimental mixed-valence iron chalcohalide compound combining iron, selenium, and bromine into a layered or framework structure. This material belongs to an emerging class of hybrid inorganic compounds studied primarily in condensed-matter physics and materials chemistry research, where the interplay between magnetic iron centers, chalcogenide bonding, and halide coordination creates tunable electronic and magnetic properties. While not yet established in commercial engineering applications, such iron chalcohalide systems are of research interest for potential applications in solid-state electronics, magnetic devices, and catalysis, though practical manufacturability and stability at scale remain open questions.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
